We just purchased a Rushmore 35RL but some things are still a bit confusing.
Can someone help me here?
Some of the labels are missing or faded to a point I cannot tell what is what.
Top left, I got that, fresh city water. Lower left, got that too, black tank flush.
What is the left center connection for?
What are the 3 valves in the center right?

Tried to reference the owners manual, but that thing is about as worthless as....well it is just worthless.
